Like many, I really covet the Panasports, but am unwilling to fork over that kind of money.   I found some 15" and 16" Rota RB wheels with the right offset, actually -4.  I don't want extremely low profile tires, as it make the wheels look too modern for the car (to me).  Probably 205 or 215 55's or 60's I do not want to lower the car either.  Does anyone have any pics of z's on 15's 16's, not lowered.  Of course I don't want it to look too tall, or have too much space b/w the top of the tire and the wheel well.  I realize that it's all subjective.  BTW, I am not racing, just driving hard on some of my favorite twisties around town.  I want to leave the ride height the way it is so I can put on the original wheel/hubcap set up and it look original if I choose.  Thanks for your help, Adam
